4 SEPTEMBER WAY Price Paid vs. HPI Average

The below graph shows the average detached house price in the Harrow local authority area over time, sourced from the HPI. The three 4 SEPTEMBER WAY sales between May 1996 and November 2006 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the September 1998 sale was for 26% below the HPI. So the extrapolation line tracks at 26% below the HPI over time, until the November 2006 sale, where it falls to 28% below the HPI. The line then continues to track at 28% below the HPI.

What might 4 SEPTEMBER WAY be worth now?
